[Matplotlib-users] Animation examples

Hello,

I would like to contribute with the following examples for animations. Compared to some that I have found, they work with both dialogs and saving a file (without phantom artists). They do not redraw the whole canvas, but they do remove and recreate the original artist. I tested this on Parabola GNU/Linux 4.19.75-gnu-1-lts, Matplotlib 3.1.1, Python 3.7.4, qt5ct (Qt version 5.13.1). I don't know if a license is required, but just it case, take GPL version 3.

(Attachment time_series_anim.py is missing)

(Attachment imshow_anim.py is missing)

Edgar,

Thanks for sending these along. Matplotlib falls under a BSD license, so we’d need you to accept that before we could include them in the code base.

The best way to get these into the code base is by submitting a PR on Github. We have a guide to contributing to matplotlib’s development and documentation here:

https://matplotlib.org/devdocs/devel/contributing.html

Cheers,

-Paul

Thanks, Edgar. Hopefully you find someone who will write the PR for you.

The matplotlib development team is well aware of the differences between permissive licenses and copy-left licenses.

Hi Paul,

Thank you for your answer. I changed the license to BSD. I

don’t have a Github account, because I don’t want anything

to do with Micro$oft, G◉◉gle, etc. I leave this for the

uninformed:

   “The two major categories of free software license are

   copyleft and non-copyleft. Copyleft licenses such as

   the GNU GPL insist that modified versions of the

   program must be free software as well. Non-copyleft

   licenses do not insist on this. We recommend copyleft,

   because it protects freedom for all users, but

   non-copylefted software can still be free software,

   and useful to the free software

   community.”–[[https://www.gnu.org/licenses/bsd.html](https://www.gnu.org/licenses/bsd.html)]



   “…using a different license for your modifications

   often makes that cooperation very difficult. You

   should only do that when there is a strong reason to

   justify it.



   One case where using a different license can be

   justified is when you make major changes to a work

   under a non-copyleft

license.“–[https://www.gnu.org/licenses/license-recommendations.html]

Hi Edgar,
Would you be opposed to sharing these on our discourse? We’ve got a forum for showcase examples: https://discourse.matplotlib.org/c/showcase

Also, could we share these on social media? Particularly the Matplotlib Instagram account? https://www.instagram.com/matplotart/

Thanks,

Hannah

FWIW, and speaking as a longstanding advocate of BSD, I think that the second part of this sentence:

In my experience, the benefits of collaborating with the private sector are real, whereas the fear that some private company will “steal” your product and sell it in a proprietary application leaving you with nothing is not.

has changed in recent years. Python is massive and in my field, for example, microscope manufacturers are bundling the Scientific Python ecosystem in their proprietary software that is then sold on for tens of thousands of dollars — per year, because subscription software is the thing now.

imho, at a minimum, direct modifications to the software should always be contributed back. John Kirkham recently pointed me to the Mozilla Public License (MPL) that makes that requirement, while still allowing proprietary code to be distributed together with the open source component. I need to stew on this more, but I might start advocating for that instead.

Thanks, Paul. I assumed that. The quotes were meant for "the uninformed" :stuck_out_tongue: . Thank you for Matplotlib in the name of countless students, reseearchers and many others.

I honestly don't know and I think this question needs to be posted to the

What would you say about changing the policies from:

       to outside parties your personally
       identifiable information. This does not
       include trusted third parties who assist us
       in operating our site, conducting our
       business, or servicing you, so long as those
       parties agree to keep this information
       confidential. We may also release your
       information when we believe release is
       appropriate to comply with the law, enforce
       our site policies, or protect ours or others
       rights, property, or safety. However,
       non-personally identifiable visitor
       information may be provided to other parties
       for marketing, advertising, or other uses.

to something like this?:

Edgar,

I am glad you carefully read the ToC, however I am unwilling to consider changing them without having a lawyer review the changes.
